i SPECIFICATION forming part of Letters Patent'No. 760,607, dated May 24, '1904.

Application filed December 16, 1902. Serial No. 135,401. (No model.) l

To a/Zliuhom if wea/y concern:

Be it known that we, WILLIAM S. BoNsALL and LE ROY C. BoNsALL, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and Commonwealth of Pennsylvania, have invented a new and useful utensil which we call a Food-Warmer, for use in connection with cooking-stoves, and' especially those stoves using oil, gas, or other vapor as a fuel, of which the following is a specification.

Our invention relates to that class of utensils intended to economize and utilize the heat otherwise wasted and to increase the heating- The object of our invention is to facilitate the keeping of articles of food warm after they have been cooked on an oil, gas, or other vapor stove while the burners are in use for cooking other articles. The difficulty to be overcome is that without some such device the articles first cooked grow cold while others are cooking unless served immediately. We are aware that there are various devices on the market to accomplish this object; but we seek to accomplish it iny a `novel and better way and do so by a machine, box, or pan which we call a food-warmer, by which an extended heated surface is securedwithout an additional consumption of fuel.

The accompanying drawings illustrate our invention, in which- Figure 1 isa view in perspective of a portion of thetop and sides of an ordinary gasstove lwith the usual shelf or bracket attached to one side and with our food-warmer resting on the top of the stove and projecty ing over the side of the shelf while it still ing the diagonal metal strips running from either side part way across the pan and supporting the top and forming, with the top and bottom of the pan, a passage for the' hot air.

Similar letters refer to similarparts throughout the several views.

A is the body of the gas or other stove. 'l is the top; O O, openings for burners; S, the detachable shelf; f f, the heat-passage; le

.handles of food warmer; 12 top of foodwarmer; Z1, the bottom; CZ 0l', diagonal strips each extending about two-thirds of the distance across'the pan from opposite sides.

e represents a series of perforations in one side of. the food-warmer.

TheV food-warmer is made of light sheetv metal of a size suitable to the stove on which it is to be used, with low sides and only onethird of a bottom. The top t is supported by the diagonal metal strips (Z d between the top and bottom and extending about two-thirds ofthe way across the food-warmer from either side and in front of the perforations e. The use of the diagonal metal strips d 0l is to form, with ajportion of the top and bottom of the food-warmer, a heat-passage, so that the heated air is drawn through the perforations e -in the side, thoroughly warming the end farthest from the iiame.

The use and operation of the food-warmer arel readily seen by placing it o'n the stove in any position-a g., in the position shown in Fig. l-when, the heat from the burners covered by it will strike the top and being confined by the closed end, top, and sides of the pan and the top of the stove pass between the top tand the bottom Y), around the ends of the diagonal metal strips d 0l', through the passage formed by said strips and theto'p and bottom. of the utensil, and inally out through the perforations e, thoroughly heating in its vices for this purpose, thereby materially increasing the heating-surface of the stove.

What We claim as our invention, and desire to secure by Letters Patent, is

1. A food-warmer, comprising a boX or pan having an impef'forate top and also having that portion of its bottom adjacent to one of its ends covered to provide a passage for the heat of a stove when the Warmer is placed thereon, the end of the box or pan adjacent to the covered portion of the bottom being provided with a series of apertures for the exit of the heat, and diagonal strips arranged Within the looX or pan and projecting from opposite sides thereof' in advance of said perforations to compel the heat in its passage through the boX or pan tozfollow a circuitous path to' e'ect its thorough distribution.

2. A food-Warmer, comprising a boX or pan having an imperforate top and also having that portion of its bottom adjacent to one of its ends covered to provide a passage for the heat of a stove when the warmer is placed thereon, the end of the box or pan adjacent to the covered portion of the bottoni being provided with a series of apertures for the eXit of the heat, and diagonal strips arranged within the boX or pan and projecting from opposite sides thereotl in advance of said perforations to compel the heat in its passage through the box or pan to follow a circuitous path to eiect its thorough distribution, the free ends ot said strips projecting beyond each other, whereby said strips overlap.

In testimony whereof` we have signed our names to this specification in the presenceof two subscribing witnesses.
